Struct IbvMemoryRegionView 

pub struct IbvMemoryRegionView {
    pub virtual_addr: usize,
    pub rdma_addr: usize,
    pub size: usize,
    pub lkey: u32,
    pub rkey: u32,
    pub device_name: String,
    /* private fields */
}

A cloneable handle to a slice of registered memory: the keys and addresses a peer needs, plus an Arc<dyn IbvMemoryRegionKeepalive> keepalive.

Cheap to clone; every clone shares the same guard, so the backing registration stays alive (and registered) until the last clone drops.

Fields

virtual_addr: usize

Virtual address in the local process address space.

rdma_addr: usize

RDMA address, possibly offset from the region’s base MR address.

size: usize

lkey: u32

rkey: u32

device_name: String

Name of the RDMA device the view’s protection domain is on.

Implementations

impl IbvMemoryRegionView

pub fn try_slice(&self, offset: usize, size: usize) -> Result<Self>

Returns a view of size bytes starting at offset.

The slice shares the same registration, keys, and device, and keeps the registration alive.

Trait Implementations

impl Clone for IbvMemoryRegionView

fn clone(&self) -> IbvMemoryRegionView

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IbvMemoryRegionView

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<&IbvMemoryRegionView> for IbvRemoteMemoryRegionView

fn from(view: &IbvMemoryRegionView) -> Self

The wire transport details are fully derived from the registered MR view: the remote key, the RDMA address, the size, and the device name.
